Must-Have Skills and Qualifications:

• 3-4 years of professional experience as a Front-end Developer, with a demonstrated focus and strong portfolio showcasing significant projects built with React.js.
• Expert-level proficiency in React.js (Hooks, Context API, component lifecycle, performance optimization) and Next.js (SSR, SSG, routing, API routes).
• Strong command of modern JavaScript (ES6+) and TypeScript for building type-safe and maintainable React applications.
• Extensive experience with state management libraries such as Redux (Redux Toolkit), Zustand, or advanced use of React Context API.
• Proficient in consuming and integrating with RESTful APIs within a React application, including asynchronous operations and error handling.
• Solid understanding of responsive design principles and best practices for building adaptive UIs across various devices.
• Expertise with version control systems, particularly Git, including advanced branching, merging, and pull request workflows.
• Familiarity with web performance optimization techniques specific to single-page applications and React, including code splitting and lazy loading.
• Understanding of UI/UX design principles and a proven ability to collaborate effectively with design teams to implement their vision precisely.
• Exceptional problem-solving, analytical, and debugging skills, with a keen eye for detail.
• Excellent communication, collaboration, and interpersonal skills.

Preferred Skills:

• Experience with front-end build tools and bundlers (e.g., Webpack, Vite) specifically configured for React applications.
• Familiarity with front-end testing frameworks for React components (e.g., Jest, React Testing Library, Cypress).
• Experience with continuous integration/continuous deployment (CI/CD) pipelines for React applications.
• Knowledge of server-side rendering (SSR) and static site generation (SSG) in depth with Next.js.
